Abstract
In July, 2000, Spencer Trennert found a mammoth tibia on Nicholson Peninsula, N.W.T.— to the southeast but still in the lee of the Tuktoyaktuk Peninsula, on the Arctic coast of western Canada. He found it lying on the gravelly beach and surmised that it had eroded from the 18-24 m-high cliffs of cobbles and sands farther back yet from the shore. His sister, Brendalynn Trennert, brought it to the Provincial Museum of Alberta for identification. The immature right tibia is from a 12-16 year old, judging by the missing, unfused distal epiphysis. It was compared with some smaller-than-"standard" mammoths from Russia and judged to have potential for growth to a "standard" size; it was young but not a dwarf. A conventional 14C date on collagen from dense cortical bone yielded a result of almost 34,000 yBP (del 13C-corrected). A review of late Pleistocene fossil finds from along the coast revealed that this is one of the oldest dated Pleistocene fossils in the region. Recoveries from the coast are uncommon relative to the hordes of bones found along major watercourses like the Old Crow and Porcupine rivers in the Yukon.
